在WordPress发布的第一段和第二段之后添加广告

问题描述

我希望有人可以解决这个问题。我的functions.php文件中有以下工作代码，可将Adsense广告放在每个帖子的第一段之后。我希望有人知道如何调整此代码，使我也可以在第二段之后添加另一个广告。简而言之，我希望在第一段和第二段之后投放广告。

I'm hoping someone can help with this question. I have the following working code below in my functions.php file to put Adsense ads after the first paragraph of each post. I'm hoping someone knows how to tweak this code to enable me to also add another ad after the second paragraph. So, in a nutshell, I want ads after the first and second paragraph.

谢谢...下面的代码。

Thanks.....code below.

//Insert ads after first paragraph of single post content.
add_filter( 'the_content', 'prefix_insert_post_ads' );
function prefix_insert_post_ads( $content ) {

    $ad_code = '<div>Ads code goes here</div>';

        if ( is_single() && ! is_admin() ) {
            return prefix_insert_after_paragraph( $ad_code, 1, $content );
    }

    return $content;
}

// Parent Function that makes the magic happen
function prefix_insert_after_paragraph( $insertion, $paragraph_id, $content ) {
    $closing_p = '</p>';
    $paragraphs = explode( $closing_p, $content );
    foreach ($paragraphs as $index => $paragraph) {

        if ( trim( $paragraph ) ) {
        $paragraphs[$index] .= $closing_p;
    }

    if ( $paragraph_id == $index + 1 ) {
        $paragraphs[$index] .= $insertion;
    }
}

 return implode( '', $paragraphs );
}

推荐答案

下面是完整的代码：

function prefix_insert_after_paragraph2( $ads, $content ) {
    if ( ! is_array( $ads ) ) {
        return $content;
    }

    $closing_p = '</p>';
    $paragraphs = explode( $closing_p, $content );

    foreach ($paragraphs as $index => $paragraph) {
        if ( trim( $paragraph ) ) {
            $paragraphs[$index] .= $closing_p;
        }

        $n = $index + 1;
        if ( isset( $ads[ $n ] ) ) {
            $paragraphs[$index] .= $ads[ $n ];
        }
    }

    return implode( '', $paragraphs );
}

add_filter( 'the_content', 'prefix_insert_post_ads' );
function prefix_insert_post_ads( $content ) {
    if ( is_single() && ! is_admin() ) {
        $content = prefix_insert_after_paragraph2( array(
            // The format is: '{PARAGRAPH_NUMBER}' => 'AD_CODE',
            '1' => '<div>Ad code after FIRST paragraph goes here</div>',
            '2' => '<div>Ad code after SECOND paragraph goes here</div>',
        ), $content );
    }

    return $content;
}
